7 Claims. l

This invention relates to improvements in hose nozzles.

A primary object of theinvention is to provide a highly versatile nozzleattachable to a garden hose which is so designed that (1) the flow ofwater through the nozzle can be regulated by the nozzle or shut offentirely; (2) the stream of water discharged may be in the nature of athin but forceful stream; (3) the stream discharged from the nozzle maybe in the form of a ne spray; or (4) the stream discharged may be in theform of a wide stream having noy great velocity and suitable for needingpurposes.

Another object of the invention is to provide a nozzle which. althoughit has threads to adjust the positions of the various parts thereof, hasthese threads entirely enclosed within the nozzle so that. none of thethreads will be exposed to dirt which might work between the threads andgell them .or otherwise reduce the life of the nozzle.

Still another obieot of the invention iS to provide a nozzle wherein theouter end of the nozzle is threaded for the application either of anadditional hose length orY various types of Spraying devices forspraying inseotiodes and the like, and utilizing Water pressure for thispurpose.

Still another object of the invention is to provide a hose nozzle ofrelatively simple and durable design which can be easily and.economically manufactured.

With the foregoing `and other objects in view, which will be mademanifest in the following detailed description .and specifieallypointedout in the appended claims, reference is had to the accompanyingdrawings for an illustrative embodiment of the invention, wherein:

Figure l is a longitudinal vertical section through the nozzle embodyingthe present invention illustrating parts thereof in one position;

Fig. 2 is a View similar to Fig. 1, but illustrating the parts of thenozzle in one position; and

Figs. 3. 4j and 5 are vertical sections taken substantially upon thelines 3 3, 4--4, and 5 5, respectively, on Fig. 2.

Referring to the accompanying drawing wherein similar referencecharacters ldesignate similar parts throughout, the improved nozzleconsists of a sleeve It internally threadedas at Il forattachment to thecoupling I2 on a'hose end of a hose I3. Within the sleeve Itr there isformed a valve seat I lt. The conventional hose washer l5 is shown asdisposed between the hose `coupling i2 and the internal shoulder on thesleeve I0 on which the Valve seat I4 is formed. A barrel IB has one endthereof telescopically disposed within the sleeve l0 and is rotatablymounted thereon. `This barrel is externally grooved as indicated at I'Ito receive a split ring I8. One or more screws I9 extend through thesleeve I0 into the lsplit ring I8. As the split ring I8 is freelyslidable within the-groove I'I, this connection afforded by the screwsIe and the ring I8 enables the barrel I6 to be rotated relatively to thesleeve I0, although it will be held against longitudinal displacementrelatively thereto. A rubber sealing ring 2G is mounted on the inner endof the barrel f6 and is engageable with the interior of the sleeve andserves to prevent leakage between the sleeve and the barrel.

Within .theharrel I6 there is disposed a spider 2l that. is rigidlysecured in position therein Such 21S.. by soldering or brazing. Thisspider carries a stem 22 which is threaded with relatively coarsethreads 23. Preferably, the threads on the stem 22 are in the nature ofgrooves cut thereon. A closure is threaded onto the stem consisting of asheet metal sleeve 24 that is provided With threads which arecomplementary to the threads 23. These threads are preferably formed byrolling or inwardly deforming the metal of the sleeve 24. The sleeve 24carries a pin 2-5 having a head 26, and a washer 21 which constitutesthe closure is slipped onto` the pin 2 5 by being stretched slightlyover the head 25. This washer is formed of rubberor rubber-likelmaterial so as to possess some 'degree of elasticity and when releasedit contracts about the pin 25 and is consequently retained thereon bythe head 26.

'The sleeve 2.4 has secured thereto a diametrically extending pin 2l,one end of which is slidably disposed between guides 23 and 29 that arement ofthe closure with respect to the sleeve.

Consequently, if the barrel it is rotated relatively to the sleeve I thestem.22 will be turned with the. barrel, causing the sleeve 2i and thewasher Zito. be moved toward or away from the seat ill 'depending uponthe direction of rotation'of the sleeve i6. .21:seats on the seat I4 asindicated in dotted vlines on Figi, thus shutting oli flow through the:nozzle entirely. @n the other hand, if the barrIn extreme position theWasher rel I6 is rotated in the opposite direction from this extremeposition the closure may be retracted from the seat I4 a variabledistance so as to regulate the volume of ilow through the nozzle. Inthis manner flow through the nozzle can be regulated at the nozzleitself as distinguished from the conventional hose nozzle wherein theiiow through the nozzle must be regulated by regulating the faucet towhich the hose is connected.

A second sleeve 30 is provided into which the other end of the barrel I6telescopically extends. This end of the barrel I6 is likewise grooved asat 3l to receive a split ring 32. One or more screws 33 extend throughthe second sleeve 3l) into the split ring 32, thus forming a rotatablebut non-slidable connection between the second sleeve 3U and the barrelI6. Leakage between the second sleeve and the barrel may be prevented bya sealing ring 34 that is applied to the extreme end of this end of thebarrel I6. The spider 2l also serves to support a threaded stem 35 thatis similar in formation to the stem 22 but which extends toward theouter end of the nozzle. A sleeve 3E having thread formations formed onits interior, such as by rolling is threadedly mounted on this secondstem 35. The sleeve 36 carries a head 3l that is capable of passingthrough the orice 38 of a surrounding throttling nozzle 39. Thethrottling nozzle has a tubular portion that is slidably disposed overthe sleeve 36. It is urged into its outermost position by a lightcompression spring 40, although the use of this compression spring isnot invariably essential. The throttling nozzle has a slidable butnon-rotatable connection with the sleeve 36,

this being provided by a rivet 4I extending diametrically through theclosed end of the sleeve 36 and into diametrically opposed slots 42formed in the sides of the tubular portion of the throttling nozzle. Thethrottling head has an outwardly extending flange in which is disposed asealing ring 43 adapted to eng-age and seat on a seat 44 on a nipple 45that is attached to the outer end of the second sleeve 30 and renderedrigid therewith. Preferably, the outer end of the throttling nozzle isbeveled outwardly around the orice 38.

Means is provided for forming a slidable but non-rotatable connectionbetween the throttling nozzle 39 and the second sleeve 30. To this endthe throttling nozzle is equipped with a laterally extending pin 4B, theend of which is disposed between ways 4l and 48 that are rigid with theinterior of the second sleeve 3B. The nipple 45 is preferably externallythreaded either for the application of an additional hose length or forthe application of various types of spraying devices that are applicableto a hose coupling I2. These spraying devices frequently utilize waterpressure to discharge insecticides, fungicides, and the like, and may beapplied to the nipple 45 without requiring detachment of the nozzle fromthe hose coupling I2.

The operation of the improved nozzle is substantially as follows.

As previously explained rotation of the barrel I S with respect to thesleeve Il) will involve movement of the closure provided by the washer21 toward or away from the seat I4. Thus flow through the nozzle can beregulated or completely shut oir by the rotation of the barrel I6. Whenthe ilow has been regulated to the desired volume the type of spray orstream discharged can be adjusted by rotation of the second sleeve 30with respect to the barrel I6. Rotation of the second 4 sleeve 30 in onedirection causes the throttling nozzle 39 to rotate therewith and as thethrottling nozzle has a non-rotatable connection with the throttlinghead 3'I the throttling head will be caused to rotate therewith withrespect to the stem 35.

In Fig. 1, the throttling head 3l is shown in its extreme forwardposition and in its extreme position the throttling nozzle 39 is seatedon the seat 44. Flow through the nozzle consequently can only take placethrough apertures 49 in the sides of the throttling nozzle and throughorifice 38. In this position the stream that issues from the nozzle isin the form of a nely divided, conical spray. If the second sleeve 30 isthen rotated to rotate the throttling nozzle 39 and consequently thethrottling head 31, the throttling head may be caused to assume aposition retracted through the orifice 38 but leaving the throttlingnozzle 39 still seated on the seat 44. In this position flow is stillconned through the apertures 49 and the orice 38 but by reason of theretracted position of the throttling head 3l, the stream that issuesthrough the orice 38 will be in the nature of a relatively narrow, solidstream of high velocity. If rotation of the second sleeve 30 iscontinued the throttling head 3l will be retracted to the position shownin Fig. 3, where the ends of the rivet 4I reaching the ends of the slots42 will retract the throttling nozzle 39 from the seat 44. In thisposition flow may take place partially through the apertures 49 and theorice 38 and partially around the throttling nozzle so that the streamthat issues from the nipple 45 will be a full stream of relatively lowvelocity suitable for ilooding purposes.

From the yabove-described construction it will be appreciated that theimproved nozzle is highly versatile in that flow through the nozzle canbe regulated at the nozzle itself or shut off completely. Furthermore,by the adjustment of the second sleeve 3o relatively to the barrel I6,either a fine conical spray may be delivered, a narrow, solid stream ofhigh velocity can be delivered, or a wide full stream of low velocitymay be delivered. The design is such that although threaded connectionsare employed at the stems 22 and 35, these threads are housed within thenozzle. No portions of them are exposed on the exterior of the nozzleand, consequently, they are not subject to damage or dirt which mightwork into the threads if the nozzle were dropped into mud or the like.

Once that the nozzle is attached to a hose it may be permitted to remainattached thereto indenitely inasmuch as the ilow issuing from the nozzlewhen it is adjusted into the position shown in Fig. 2 is very much thesame as the iiow that issues from a, garden hose with no nozzle attachedwhatsoever.

The stems 22 and 35 may be formed integral with the spider 2| and thespider secured in position within the barrel I6. In the alternative, thestems 22 and 35 may be made integral with each other and tted into thespider 2| with a force t, the spider 2I being made as a stamping. Alsoit is possible to construct the barrel I6 with the spider 2I integraltherewith and force the stems 22 and 35, which are integral with eachother, into the spider with a force fit.

Various changes may be made in the details of the construction withoutdeparting from the spirit and scope of the invention as defined by theappended claims.
